What is happening in centos 5 with network config files??? I have a machine with 2 network cards. ifcfg-eth1 keeps changing to DHCP. All my static setup is gone. Why is it doing this? How can I stop it? I run "netconfig -d eth1" and re-setup my static information. I reboot and now I am back to DHCP. I have a gigabyte motherboard, nvidia chipset. forcedeth driver. eth0 is e1000.

How can I stop it?I had exactly this problem with CentOS 4 on a machine that has 2 onboard NICs plus a third NIC on a card. Now if I can just remember what I did ... The problem (as I recall) is that on each reboot the onboard NICs are being discovered in a different order, so the MAC addresses in /etc/sysconfig/hwconf don't match what is recorded in /etc/sysconfig/network-scripts/ifcfg-eth*. I believe what I had to do (I should have written it down, damn it) was hand-edit /etc/sysconfig/hwconf to completely remove all the references to the NICs (there may be more than one entry for each NIC because of the flip-flopping), edit ifcfg-eth* to remove all references to HWADDR, reboot again to let the cards be rediscovered, and then again hand-edit ifcfg-eth* to insert HWADDR lines that match the device assignments in the regenerated /etc/sysconfig/hwconf. However, I may have at least the last step of that wrong.

It was being blamed on Asus bios issues, but it might be a bug in the forcedeth driver. The suggestions I have seen involved putting a fixed MAC address into that interfaces config file. -- MailScanner is like deodorant...

i believe i had mentioned this already on this list:
have had same problems with my asus m2npv-vm board (onboard forcedepth
nic) the first days with the board under fedora 6 - would say no big
diff's to centos-
the fedora way goes:
1. move or delete /etc/sysconfig/hwconf
2. move or delete /etc/modprobe.conf
3. run kudzu afterwards => this writes new hwconf, modprobe.conf
4. bring your nic's down: ifdown ethx
5. remove the driver via modprobe -rv <your-nic-driver> (forcedepth)
5a. maybe to be sure: lsmod|grep -i <your-nic-driver>
6. reload the driver via modprobe -sv ...
7. fix your mac-addr-settings via system-config-network
8. compare your mac's in hwconf _and_ via ifconfig
steps 4-6 are also performed via reboot (grrrrrrrrrr: m$ world tasks),
but your are able to exclude if this files were changed again after step
3. (ls -l /etc/sysconfig/hwconf => date/time !)
a hint of another problem !
if there are still diff's, then it's another problem i don't know a
solution for, yet, but i remember ethx order changes and therefore mac
mismatches at late fedora 5/early fedora 6 kernels.
try and report !
okay ?

However, sadly it did not work. Also I see no way in the system-config-network to set a MAC address. I was in the character mode here not X. This is SOOO bizzar. Again, when I started I had 2 Asus M2N-MX boards. One was giving the invalid MAC address and one seemed OK. Both had the forcedeth driver loaded for onboard network. I bought 2 gigabyte motherboards (DIFFERENT BIOS) and I have the same issue. One board is working and the other is giving the invalid MAC address. Both gigabytes have the forcedeth driver. I tried loading centos 4 but it does not even recognize the forcedeth device at all. even manually loading. I'm at a loss. I have a script file that runs and sets things up the way I want after boot up. Not pretty - but I guess it works. Jerry
